Floatation devices are tools designed to help individuals stay afloat in water. They are commonly used in activities like swimming, boating, and water sports. Examples include life jackets, buoyancy aids, and inflatable rafts. These devices work by providing buoyancy, which counteracts the force of gravity, allowing a person to remain on the surface of the water. Life jackets are a specific type of floatation device that is often required by law on boats. They are designed to keep a person’s head above water, even if they are unconscious. Other floatation devices, like pool floats and surfboards, are used for recreation and fun, enhancing safety while enjoying water activities.
